Notifications history

Do you know how to access your Notification Center? With the iPhone unlocked, swipe downwards from the top center of the page. Your Notification Center will appear and any notification that was not acknowledged should appear there, until you clear them. See this. View and respond to notifications on iPhone - Apple Support

Unless you have your notifications set for Temporary and do not have the set to remain in Notification Center, they will not disappear, until you have acknowledged them. Also, any app that has a notification will have a badge associated with it. If you do not see any of that, then you have not missed a notification.

You cannot.
